Hi. because of the new releases of shell utils the old files are removed ( eg 2.0.11) so an emerge shell-utils fails. Perhaps u can change the file location in the 2.0.11 ebuild file and/or update shell utils ebuild to version 2.0.14 ( i would do it myself but i saw that there is a gentoo specific patch file and im not shure about the dependecies so perhaps someone who knows the problem does ist)
added to portage and masked. please test.
